This chapter examines how local food systems can empower Black farmers and growers through direct-to-consumer and community-based markets, analyzing tools like farmers’ markets and urban agriculture. While case examples show Black-led initiatives, persistent barriers include limited capital, discriminatory pricing and lending, bureaucratic gaps, and uneven USDA support despite civil rights settlements. The study details these challenges.

This study investigated the role of vertical urban agriculture in promoting the right to food in Brazil, considering the food system crisis as a problem affecting the right to the city. An inductive method with a qualitative approach, including literature review, documental research, and case studies from Japan, Singapore, Germany, the USA, and Brazil, revealed that vertical urban agriculture has "cons" when appropriated as a profitable system with restricted access products, and "pros" such as occupying vacant urban land and being produced by or supporting poor families.

Jeong D., Li L., Perez-Quesada G. · Choices Magazine (Agricultural & Applied Economics Association), 2nd Quarter 2026 · United States

An analysis of community garden siting through an environmental cost-benefit framework, organised around two direct costs (land and water) and two externalities (water pollution and gentrification). Cheap vacant parcels can carry remediation and infrastructure costs that exceed those of pricier development-ready sites over a garden's planning horizon, and in arid regions irrigation can be up to 34% of annual maintenance cost. On the externality side, weak nutrient management lets nitrogen and phosphorus accumulate and risk groundwater contamination, and community gardens can raise adjacent property values by 3–4% initially and around 7% within five years, potentially displacing the lower-income residents they are meant to serve. The authors note that the absence of a comprehensive geo-referenced inventory of community gardens — with establishment dates, tenure arrangements and management practices — constrains rigorous cost quantification and causal analysis.

This study analyzed how urban agriculture contributes to green gentrification in Montréal. Based on interviews with planners, developers, and community actors, and discourse analysis of municipal policy documents, it showed that ecological initiatives are prioritized over housing, and sustainability fixes reconcile progressive rhetoric with growth imperatives, leading to policy trade-offs that undermine housing affordability. These findings reveal how progressive governments reproduce structural injustices through their ecological transition agendas within the context of a housing crisis.

Clara Camargo · Revista Latino-americana de Geografia e Genero · Brazil (São Paulo)

This study investigates the socioeconomic profile and agroecological production strategies of female urban farmers in São Paulo's peripheral territories, using Feminist Economy Theory and Ecofeminism perspectives. It highlights that while these women are crucial for food security and green spaces, they remain largely invisible in economic theories and have limited access to public policies due to their non-generation of direct monetary income. The methodology included participant observation in RAPPA meetings, semi-structured interviews, and guided tours of women-led production units.

Pierric Calenge, Maie Gérardot · Métropolitiques · United States (Cleveland)

The work by Max Rousseau and Vincent Béal illuminates the ambiguities of a policy that organizes urban decline and racial segregation in Cleveland. This policy promotes urban degrowth and racial segregation, balancing algorithmic management and urban greening. The study focuses on the Rust Belt region, which experiences de-urbanization marked by the subprime crisis, racism, and segregation.

Shawn A. Trivette, Shannon McCarragher · Renewable Agriculture and Food Systems · United States (New England)

This paper examined three types of locally oriented Short Food Supply Chains (SFSCs) in southern New England and their spatial alignment with demographic factors. The findings indicate that pay-as-you-go operations are more prevalent in predominantly White areas and, to some extent, higher-income areas. Box share arrangements (community-supported agricultures) showed stronger associations with educational attainment. The study concludes that local food availability is a systematically uneven phenomenon, varying with both outlet type and social characteristics.

Rob Roggema, Aleksandra Krstikj, B. J. Erazo Flores · Nutrients · Mexico (Monterrey)

This study in the Noreste of Mexico, focusing on Monterrey, investigated spatial and non-spatial barriers to adopting healthy diets and accessing plant-based foods. Findings revealed significant disparities in food access across the Monterrey metropolitan area, with central urban zones having superior access to fresh foods compared to suburban and peripheral regions. This inequality disproportionately affects marginalized areas with higher poverty rates, worsening food insecurity.

This scoping review explored factors associated with Community Supported Agriculture (CSA) participation among low-income households in the United States. Analyzing 18 articles, findings suggested that women may be more likely than men to enroll in CSA. A lack of familiarity with CSA may hinder enrollment, whereas more education and self-efficacy for food preparation may facilitate participation.

Domenic Vitiello · Urban agriculture · United States

US cities have developed urban agriculture support systems reflecting competing values, with some prioritizing public good and others economic gains. A chapter reflecting on urban agriculture planning in Chicago and Philadelphia notes that institutional structures significantly impact equity and justice. The study indicates that the existing urban agriculture support systems in these cities may not adequately promote equity and justice.

A study of 18 urban community gardens in Central Coast, California, USA, used gardener surveys and field measurements to evaluate food production and its distribution. Gardeners produced an average of four pounds of food per week, saving an estimated $16 USD weekly. However, gardeners with greater food insecurity (larger families or lower incomes) were not the largest producers, indicating uneven benefit distribution despite high overall productivity.

This study reviewed and categorized 73 food asset maps in Canada based on their included food assets and design characteristics. Most maps included built environment assets like grocery stores and food banks, as well as agriculture-based natural food assets such as farms, community gardens, and orchards. However, representations of Indigenous-focused food assets and non-agriculture-based natural food assets like forests, water bodies, and foraging areas were generally lacking. This lack of Indigenous perspectives reinforces the values of a settler-colonial food system within food asset maps.

This study interviewed 17 urban growers and local food advocates in predominantly Black communities in Chicago to understand barriers to accessing healthy food through urban agriculture. Key barriers identified were the lack of accessibility to traditional food retailers, the high availability of processed foods, and issues with the cultural acceptability of urban-produced foods. The research highlights significant challenges faced by these communities in accessing healthy food despite urban agriculture's potential.

This descriptive analysis identified gentrifying areas in Vancouver, Calgary, and Toronto, Canada, from 1996–2006 and 2006–2016, to determine the prevalence of greening interventions. The study found that greening, including parks, cycle lanes, and community gardens, frequently occurred before, during, and after gentrification. These results indicate that greening is common in gentrifying areas throughout the gentrification process, suggesting a need for a broader understanding of the relationship between urban greening and gentrification.

Pascale Joassart-Marcelli's book "The $16 Taco" examines how food and power intersect to create landscapes of hunger and plenty in U.S. cities, using San Diego as a case study. It argues for the centrality of food in broader structural issues of social, political, and cultural inequalities, which manifest as material inequality. The book explores the impacts of food apartheid, a system of segregation that prevents certain groups from accessing nourishment, and explains the role of racist real estate practices in devaluing neighborhoods of immigrants and people of color.

This scoping review examines funding and financing mechanisms for nature-based solutions and their impact on social equity in the United States. It finds that market-driven nature-based solutions can contribute to an inequitable distribution of urban ecosystem services. The distribution of benefits is influenced by local contexts, decision-making inclusion, and payment mechanisms, suggesting disparities in access for diverse and marginalized populations.

This GIS-based study of Kalamazoo, Michigan, analyzed how accessibility to different types of food access points — full-service grocery stores, farmers markets, community gardens, food pantries, and convenience stores — differed between low-income and higher-income census tracts. All full-service grocery stores were accessible via bus routes, but 11% of residents in low-income areas lacked adequate access, living beyond the 0.25-mile walkable distance to bus routes. "Positive" access points such as community gardens, food pantries, and farmers markets were found to be concentrated in areas that already had grocery store access, whereas "negative" access points — convenience and dollar stores, which provide lower-quality, highly processed food — filled the access gap in lower-income areas instead. More than twice as many low-income residents had walkable access to convenience stores as higher-income residents, with 81% of those convenience stores located within low-income tracts.

Just after NYC announced expansion of mandatory residential organics collection by 2024, the mayor's office eliminated funding for the city's community composting program. The article identifies three failures reflecting national trends: government 'composting' programs that actually rely on anaerobic digestion, centralized processing that concentrates environmental burdens in vulnerable neighborhoods, and mandatory government programs undercutting community composters' viability.

Hantz Woodlands, a large-scale tree farm on Detroit's east side, acquired roughly 2,600 parcels and still holds about 2,000. It bought an initial 1,550 parcels for $540,000 and later resold about 10% of its holdings for $9.5 million — nearly nine times its original cost — while paying only $7,035 of the $33,110 it owes in blight-violation fines. Critics note the Detroit Land Bank Authority never reclaimed a single Hantz property despite missed deadlines, even as it repossessed land from ordinary residents who fell behind.

K. Michelle Glowa · Journal of Agriculture Food Systems and Community Development · United States (California)

This paper reflects on the engagement between Mexican and Salvadorian farmers at the Beach Flats Garden in Santa Cruz, California, and local educational institutions. It discusses the garden's role in critical food system education, highlighting its function as a space of resistance to gentrification in a competitive land market. The garden provides examples of noncapitalist exchanges and decolonial foodways, emphasizing traditional agroecological knowledge.

This paper focuses on mobility issues in the southern region of Curitiba, Brazil. It points out that the benefits of urban agriculture, particularly the ecological advantages of short food circuits, are hindered by the isolation of its growers. The lack of accessibility in peripheral areas, due to distance or insufficient infrastructure investment, suggests a loss of opportunities in utilizing the transport system.

Daniel Sax, Lorien Nesbitt, Shannon Hagerman · Environment and Planning E Nature and Space · Canada (Vancouver)

A case study of an urban farm in Vancouver, Canada, facing displacement due to redevelopment, revealed that urban residents engaged in urban greening can be both implicated in and impacted by green gentrification processes. The study highlighted the power dynamics farm members navigate to preserve land access and found that the farm's identity was co-opted by development agents as a branding tool. This research contributes to understanding the limitations of development processes in accounting for green gentrification risks.

This study investigated the location of urban commercial farms in Chicago, Illinois, and whether there is a significant disparity between the social demographics of production and sale points. All production and distribution points for commercial urban farming companies were geocoded and analyzed against socioeconomic indicator data from the 2016 US census, including median annual household income, mean home value, and percent racialized minority population. Findings revealed statistically significant differences in socioeconomic indicators between census tracts of farm and sale point locations, showing a skewness of farm locations towards lower socioeconomic status areas and sale point locations towards higher socioeconomic status areas. This suggests that while farms are more likely to be located in marginalized neighborhoods in Chicago, most produce grown by these farms is sold in more privileged areas.

This study examined school garden prevalence in 148 K-12 schools across four low-income New Jersey cities between 2010-2011 and 2017-2018, before and after the Healthy Hunger-Free Kids Act (HHFKA) of 2010. Garden prevalence increased from 19% in 2010-2011 to 32% in 2013-2014, but this increase was not sustained over time. Furthermore, schools with a majority Hispanic student enrollment had approximately half the odds of having a garden compared to schools with a majority Black student enrollment.
